'1o claims.

This invention relates to a door stop and more particularly to a hingestop attachment therefor, although certain features thereof may beemployed with equal advantage for other purposes.

It contemplates more especially the provision of a simple, inexpensiveand improved hinge stop attachment that can be utilized in conjunctionwith standard building door hinges serving as mounts for doors that openboth parallel as well as angularly to a wall.

Numerous types of door stops have heretofore been proposed inconjunction with hinge mounts therefor, but these are expensive andrequire special hinge constructions that preclude their use with doorsof standardv construction now available and commonly usedin buildingstructures. Then, too, the hinge stops of known construction are notadaptable for use on present door constructions which are in use andcannot be advantageously changed to provide an adjustable stop thereforofknovvn construction. It is often that doors cannotV be permitted toswing to the limit of their open position against an adjacent Wallbecause there may be numerous obstructions such as the requirement toplace furniture in the path thereof.

As a result, injury is occasioned to the door as well as the furnitureunless fa positive stop is provided. This' usually takes the form of afloor mounted stop which is undesirable for numerous well known reasonssuch as impairment to the floor as Well as the obstruction occasionedthereby when the door is not in its extreme open position. Floor mountedstops as well as the customary door stops on the base-board of the wallare not entirely advantageous or desirable in that they serve asobstructions causing damage to the person as well as appliances such asvacuum cleaners,V buggies and other movable objects that are oftendisplaced in the path thereof. All of these shortcomings `render itundesirable to utilize the customary baseboard and floor mounted doorstops as well as the specially constructed hinges that have beenprovided for an equivalent purpose, the latter being too expensive asasubstitute for standard hinges and for that reason have not been adoptedto any extent. v

Numerous types' of door stop hinge attachments have heretofore beenproposed, but these for the mostrpart require special hinges and anattachment is so designed .that they must be anchored in both the doorandl .wall frames or either. in the wall or door or both usually isbeyond the ability of the average untrained individual in the home and,further, these necessitate permanent holes and cause unsightly damage tothe nish, so that the door stop cannot be removed The anchoredattachment of doorstops.

should the occasion arise therefor or in the event the further usethereof becomes unnecessary.

With the teachings of the present invention, these' undesirable featuresof'door stops have been overcome and an improved structure has beenprovided that enables the ready association thereof to a standard hingewithout any required anchorage in the wall or door frame.

One object of thepresent invention is to simplify the construction andimprove the operation of devices of the character mentioned.

Another object is to provide a durable, inex-A sisting of a plurality ofinterconnected links capable of relative pivotal displacement to arrestthe opening of a door in a variety of positions by merely serving as acomplement to a standard door hinge.

A still further object is to provide a plurality of interconnected linkshaving means, for varying the relative positions thereof to constitutean adjustable obstruction in the path ofl a door.

Still a further object is to provide doorl stop attachments capable ofapplication to standard building door hinges to predetermine thepositions of the door without resort to the usual wall or door anchoredelements.

An additional object is to provide a plurality of interconnected link-stogether with adjustable means to render such relatively collapsible andexpansible to define adjustable obstructions in the path of a swingingdoor and its frame.

kOther objects and advantages will appear from the following descriptionof -an illustrative embodiment of the present invention.

The structure selected for illustration comprises a substantiallyelongated rectangular bracket member I stamped or otherwise shaped fromsteel or other suitable material to provide normally oifset arms I I andI2 constituting in this instance integral portions of the bracket memberI0 to define horizontally spaced and vertically aligned extensionsthereof. The top and bottom bracket arms II-I2 are spaced to correspondwith the width'of the complemental hinge loops I3, I4, I5, and IIS-I1comprising parts of the standard hinge-plates I8 and ISL The hingeplates I8-I9 are maintained in assembled relation for pivotal swingingmovement relative to each other by an` interconnected pintle 20 thatterminates at its upper end in a peripheral flange 2I constituting apart of an ornamental head 22. The pintle 20 extends through thecomplemental loops I3-I4-I5 and I6-I1 of the hinge plates I8-I9,respectively, and the bottom ornamental head 23 has a pin 24 extendinginto thelower hinge loop I5 to provide symmetrical and ornamental hingepin exten- As shown, the bracket arms II-I2 receive the alignedcomplemental loops I3-I4-I5 and I6- I1 therebetween, the bracket armsII-I2 being provided with aligned bores to receive the pintle and thelower head pin 24 therethrough so that the bracket member II! isdetachably connected thereto. connected hinge plates Ill-I9 serve toswingingly mount the door to a door frame 26 of a building structure. Tothis end, the door 25 has its hinge plate I8 mounted in a countersunkend portion 21.

Similarly the door frame ,26 has its hinge plate I9 mounted in a,.countersunk end portion 28, since the countersunk end portions 21-28are provided in the-r adjacent surface of the door 25 and frame 26 as anexpedient of common practice. -Threaded screws or other suitablefasteners secure the movable hinge plates I 8-I9 to the door 25 and doorframe 26 in the custornary manner. This constitutes a standard hingemount for doors 25to-maintain them relatlve to a xed door frame 26 andusually two or more hinges I8--I9-2Il are utilized to swingingly supporta door 25 depending upon the size and weight thereof.

The number of hinges I8-I9-20 that are utilized to swingingly supportthe door 25 is immaterial, since it is preferable though not essentialthat the top hinges I8-I9-2Il of any door 25 be utilized for attachmentof the stop member bracket I Il thereto. To this end, the stop memberbracket I0 is detachably connected to the top hinge pintle 20 and anadjustable stop is mounted thereon for positioning in the It is to benoted that the inter- 3U, 3| and 32, in this instance four, which areinterconnected at their extremity by means of pivot pins 33, 34, 35 and36. The pins 34 and 36 constitute, in this instance, short rivets thatloosely interconnect the links 29-30 and 3I-32 at their laterallyprojecting extremities. The top pivot pin 33 not only interconnects theupper extremities of the links 29-3I, but also projects path betweenth-e relatively swinging door 25 y and its frame 26.

.by the screw adjusting bolt 38.

through the bracket member IU proximate to the top thereof to serve asan attaching expedient thereof.

The lower pin 35 interconects the lower extremities of the links 30-32and, further, has an inwardly projecting lug 31 constituting an integralportion thereof to threadedly receive a screw adjusting bolt 38therethrough. To'this end, the lug 31 is provided with an internallythreaded bore corresponding with the external threads on the screwadjusting bolt 38 which is journalled at its extremities in thevertically aligned bores provided in the bracket arms II- I2. To thisend, the screw adjustingbolt 38 is provided'with an enlarged upper head39 and a lower thumb knob 40 which permits the rotation of the screwadjusting bolt 38 to raise or lower the lug 31 which is pivotally.connected to the lower extremities of the links 36-32.

It will be observed that with the rotation of the screw adjusting bolt38 in one direction, the lug 31 will be elevated to spread the pivotedextremities 34--36 of the interconnected links 29-30-3I and 32. Byreversing the direction of rotation of the screwxadjusting bolt 38, thelateral movement of the link extremities 34-36 will be effected tocontract the interconnected links 29, 30, 3| and 32, thereby providing avariable spread thereto so that the link extremities 4I and 42 proximateto the pins 34-36, willbe disposed inthe path of the swinging door 25and its frame 26 (Figure 1).

As a result, the door-25 will be limited in its swinging movementrelative to the frame 26 depending upon the relative position of theinterconnect-ed links 29-30-3I-32 that is controlled So that theextremities 4I-.42 of the interconnected links 3I-32 and 29--30 will notmar the finish of the door 25 and frame 26, metallic impact sustainingplates 43 and 44 are attached by means of fasteners 45 and 46 to theconfronting surfaces of the door 25 and frame 26. over the area thereofthat confronts the link extremities III-42..

These plates 43-44 serve as a protecting shield for the door 25 andframe 26 which, for the most part, are constructed from wood thatotherwise would be injured by the impact of the link extremities 4I-42thereagainst.

In the modified embodiment sho-wn in Figure 5 the position of the stoplink actuating. member is reversed from that shown in the precedingembodiment. In this embodiment, the elongated rectangular bracket memberI0 has relatively shorter top and bottom bracket arms II-I2 spaced tocorrespond with the width of the complemental hinge loops I3', I4', I5',and |6'I1 comprising parts of the standard hinge I8' and I9 (Figure 5).As shown, the bracket arms II'-l2' receive the aligned complementalloops I3-I4'-I5 and I6-I1' therebetween and the bracket arms II-I2 areprovided with aligned bores to receive the pintle 20' and the lower headpin 24 therethrough so that the bracket member I0 is detachableconnected thereto. The bracket member I0 extends parallel to alignedhinge loops I3-I4-I5' and I6'-I1 and-in closer association therewith inthat the interconnected links 29', 30', 3| and 32' are next adjacentthereto with the top link pin 33' extending there-v through to providean outwardly projecting lug ssa.

To this end, the lug 31' confronts the upper pin lug 33EL and a lowerlug 33b anchored to the lower extremity of the bracket member I0', the

lugs 33e, 33h, and 31' being pro-vided with inter'- nally threadedaligned bores corresponding with the external threads on the screwadjusting'bolt 38 journalled at its extremities in the verticallyaligned bores provided in the bracket arms ||-l2'. To this end, thescrew adjusting bolt 38 is provided with an enlarged upper head 39 and alower thumb knob 4B' which permits the rotation of the screw adjustingbolt 38' to raise or lower the lug 31 which is pivotally connected tothe lower extremities of the links 3|l-32'.

It will be observed that with the rotation of the screw adjusting bolt38'A in one direction, the lug 31 will be elevated to spread the pivotedextremities 4|', 42 of the interconnected links 29'-3|l3 l "-32. Byreversing the direction of rotation of the screw adjusting bolt 38', thelateral movement of the link extremities 34'-36' will be eifeoted tocontract the interconnected links 29', 3B', 3| and 32', therebyproviding a variable spread thereto so that the link extremities 4|' and42' proximate to the pins 34'-36, will be disposed in the path of theswinging door 25 and its frame ZS (Figure 1). As a result, the door 25will be limited in its swinging movement relative to the frame 26depending upon the relative position of the interconnected links 29'-30'-3|'-32 that is controlled by the screw ju-sting bolt 38. l

In the still further modified embodiment shown in Figures 6 to 9, thescrew adjusting bolt 38' in the preceding embodiment, is dispensed within lieu of a more simple and inexpensive expedient. In this embodiment,the elongated rectangular bracket member lil" has relatively longer topand bottom bracket arms ||"-|2" spaced to correspond with the width ofthe complemental hinge loops I3", I4", l5", and |6"-|1" comprising partsof the standard hinge I8" and I9" (Figure 9). As shown, the bracket arms||"-l2" receive the aligned complemental loops |3"-|4"|5" and |6"-|'ltherebetween and the bracket arms ||"'-|2 are provided with alignedbores to receive the pintle and the' lower head pin 24" therethrough sothat the bracket member I8 is detachably connected thereto.

The bracket member lll" extends parallel toV the aligned hinge loops|3"'-|4"-|5" and |6"-||" in closer association therewith in thatinterconnected links 29, 30", 3| and 32" are next adjacent thereto withthe top link pin 33" this embodiment, the adjustable stop membercomprising a plurality of links 29", 30", 3|" and 32", in this instancefour, which are interconnected at their' extremity by means of pivotpins 33, 34", 35"v and 36".

The pins 34" and 36" constitute, in this instance, short rivets thatloosely interconnect the links 29m-30" and 3|--32 at their laterallyprojecting extremities. The top'pivot pin 33" not only interconnects theupper extremities of the links 29"-3| but also projects through thebracket member I0" proximate to the topI thereof .to serve as anattaching expedient thereof.-

The lower pin 35" interconnects the lower extremities of the links30"-32" and, further, has an outwardly projecting threaded shank 31"constituting an integral portion thereof. The threaded shank 31" extendsfrom a'shoulder 38" on the pin 35" which rides in an elongated slot 39provided in, thebracket member |0".

VTo this end, the shoulder 38" rides in the slot 39" within the limitsthereof to elevate the pin 35" to-spread the pivoted extremities 34"-36"of the interconnected links 29"-30"-3|" and By lowering the pin 35", thelateral move- 32". ment of the link extremities 34"--36" will beeffected to contract the interconnected links 29", 3U", 3| and 32",thereby providing a variable spread thereto so that rubber feet 4|" and42" anchored to the pins 34"-36, will be disposed in the path of theswinging door 25 and its frame 26 (Figure 1).

As a result, the door`25' will be limited in its l l swinging movementrelative to the frame 26 depending upon the relative position of thelower pin 35"' which determines the lateral spread of k theinterconnected links 29"- 3|l"3|-32 that is controlled and retained inadjusted positionwithin the slot 39" by a screw fastener 40".

It will `'be observed that the rubber extremities and 29"-3|l" will notmar the finish of the` door 25 and frame 26, and that such a resilientbumper expedient may be desirable to protect the confronting surfaces ofthe door 25 and frame 26 over the area thereof that confrontsv Various'changes may be made in the embodif ment of the invention hereinspecioally fdescribed without departing Vfrom orsacricing any of theadvantages of the invention or any features thereof, and nothing hereinshall ber construed as a limitation of the invention, its concept orstructural embodiment as to the whole or anyv part thereof except asdefinedA in the appended claims.
